Question

Two chemical species X and Y combine together to form a product P which contains both X and Y : X + Y \longrightarrow P X and Y cannot be broken down to simpler substances by simple chemical reactions. Which of the following concerning the species X, Y and P is not correct?

Answer 1

Answer:

Two chemical species X and Y combine together to form a product P which contains both X and Y, X + Y → P, X and Y cannot be broken down into simpler substances by simple chemical reaction. ... In this reaction, X and Y can not be broken down into simpler substances by chemical reactions, therefore, X and Y are elements.

Answer 2

$\huge\purple{ \underline{ \boxed{\mathbb{\red{QUESTION : }}}}}$

Two chemical species X and Y combine together to form a product P which contains both X and Y .

X + Y → P

X and Y cannot be broken down into simpler substances by simple chemical reactions . Which of the following concerning the species X , Y and P are correct ?

(i) P is a compound

(ii) X and Y are compounds

(iii) X and Y are elements

(iv) P has a fixed composition

• (a) (i) , (ii) and (iii)

• (b) (i) , (ii) and (iv)

• (c) (ii) , (iii) and (iv)

• (d) (i) , (iii) and (iv) ✔️

$\huge\purple{ \underline{ \boxed{\mathbb{\red{ANSWER : }}}}}$

(d) (i) , (iii) and (iv)

• P is a compound because it is formed due to combination of two chemical species X and Y .

• X and Y are elements because they cannot be broken down into simpler substances by simple chemical reactions .

• P has a fixed composition because it is formed due to combination of X and Y in fixed ratio .
